Mount Lockwood
Grindley Plateau () is a high icecapped plateau in the central Queen Alexandra Range of Antarctica, bordered by the peaks of Mount Mackellar, Mount Bell and Mount Kirkpatrick. Name Grindley Plateau was named by the Northern Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE; 1961–62) for George Grindley, senior geologist of the party.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Wyckoff Glacier
Lennox-King Glacier is a large valley glacier, about long that flows east into the Ross Ice Shelf. Location Lennox-King Glacier drains Bowden Névé and flows northeast between the Holland Range and the Queen Alexandra Range of Antarctica to enter Richards Inlet and the Ross Ice Shelf. The Law Glacier supplies ice to the Lennox-King Glacier, leading some glaciologists to refer to it as the Law/Lennox-King Glacier system or Law-Lennox-King glacier corridor. Its mouth is south of the Robb Glacier and west of the Beardmore Glacier. Lennox-King Glacier was named by the New Zealand Geological Survey Antarctic Expedition (1959–60) for Lieutenant Commander James Lennox-King, Royal New Zealand Navy, leader at Scott Base, 1960. Mouth Richards Inlet . A large ice-filled inlet at the mouth of Lennox-King Glacier, opening to the Ross Ice Shelf just southeast of Lewis Ridge. Named by the NZGSAE (1959–60) for R. W. Richards, a member of the Ross Sea Party of the Imperial Trans-Ant ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Plateaus Of Antarctica
In geology and physical geography, a plateau (; ; : plateaus or plateaux), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, plate tectonics movements, and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. They may be formed by upwelling of volcanic magma or extrusion of lava. The underlining mechanism in forming plateaus from up ...

Ernest Shackleton
Sir Ernest Henry Shackleton (15 February 1874 – 5 January 1922) was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration. Born in Kilkea, County Kildare, Ireland, Shackleton and his Anglo-Irish family moved to Sydenham, London, Sydenham in suburban south London when he was ten. Shackleton's first experience of the polar regions was as third officer on Captain Robert Falcon Scott's Discovery Expedition, ''Discovery'' Expedition of 1901–1904, from which he was sent home early on health grounds, after he and his companions Scott and Edward Adrian Wilson set a new southern record by marching to latitude 82°S. During the Nimrod Expedition, ''Nimrod'' Expedition of 1907–1909, he and three companions established a new record Farthest South latitude of 88°23′ S, only 97 geographical miles (112 statute miles or 180 kilometres) fro ...

British Antarctic Expedition, 1907–09
The ''Nimrod'' Expedition of 1907–1909, otherwise known as the British Antarctic Expedition, was the first of three expeditions to the Antarctic led by Ernest Shackleton and his second time to the Continent. Its main target, among a range of geographical and scientific objectives, was to be first to reach the South Pole. This was not attained, but the expedition's southern march reached a Farthest South latitude of 88° 23' S, just from the pole. This was by far the longest southern polar journey to that date and a record convergence on either Pole. A separate group led by Welsh Australian geology professor Edgeworth David reached the estimated location of the South magnetic pole, and the expedition also achieved the first ascent of Mount Erebus, Antarctica's second highest volcano. The expedition lacked governmental or institutional support, and relied on private loans and individual contributions. It was beset by financial problems and its preparations were hur ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Beardmore Glacier
The Beardmore Glacier in Antarctica is one of the largest valley glaciers in the world, being long and having a width of . It descends about from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range of the Queen Maud Mountains on the eastern side and the Queen Alexandra Range of the Central Transantarctic Mountains on the western. Its mouth is east of the Lennox-King Glacier. It is northwest of the Ramsey Glacier. Early exploration The glacier is one of the main passages through the Transantarctic Mountains to the great polar plateau beyond, and was one of the early routes to the South Pole despite its steep upward incline. The glacier was discovered and climbed by Ernest Shackleton during his Nimrod Expedition, ''Nimrod'' Expedition of 1908. Although Shackleton turned back at latitude 88° 23' S, just from the South Pole, he established the first proven route towards the pole and, in doing so, became the first person to set foot up ...

Queen Alexandra Range
The Queen Alexandra Range () is a major mountain range about long, bordering the entire western side of Beardmore Glacier from the Polar Plateau to the Ross Ice Shelf. The range is in the Transantarctic Mountains System, and is located in the Ross Dependency region of Antarctica. Discovery The Queen Alexandra Range was discovered on the journey toward the South Pole by the British Antarctic Expedition, 1907–09 (BrAE), and was named by Ernest Shackleton for Queen Alexandra, Queen of the United Kingdom, 1901-10. Shackleton and his men, and a later expedition headed by Robert Falcon Scott, both collected rock samples from the range that contained fossils. The discovery that multicellular life forms had lived so close to the South Pole was an additional piece of evidence that accompanied the publication (in 1910 and independently in 1912) of the theory of continental drift. Location The Queen Alexandra Range is bounded by the Beardmore Glacier along its southeast edge, which divi ...
